While expression symbols worked for what they are, they weren't so good
for ivar access because every ivar of a class (and its super classes)
would be accessed at method scope creation, generating spurious access
errors if any were private. That is, when the access checks worked at
all.
I don't remember what the goal was (stopped working on it eight months
ago), but some possibilities include:
- better handling of nil (have trouble with assigning into struts)
- automatic forward declarations ala C# and jai (I was watching vids
about jai at the time)
- something for pascal
- simply that the default symbol type should not be var (in which case,
goal accomplished)
